[0043]A piston ring was manufactured from a highly nitridable steel composition in accordance with the invention having the following composition:
B:0.001weight %Pb:0.16weight %C:0.7weight %S:0.009weight %Cr:18.0weight %Si:3.0weight %Cu:0.05weight %Sn:0.001weight %Mn:0.45weight %Ti:0.003weight %Mo:1.05weight %V:0.11weight %Nb:0.002weight %W:0.003weight %Ni:3.15weight %Fe:remainder
[0044]It was obtained by producing a molten mass from the starting materials (steel scrap, return scrap and alloying substances) and casting the melt into a prepared green sand mould. Next, the mould was emptied and the piston ring obtained was cleaned. The piston ring was then quenched and tempered. This was accomplished by austenitization above the Ac3 temperature of the steel composition, quenching in oil and tempering at a temperature in the range 400° C. to 700° C. in a controlled atmosphere furnace.
[0045]Finally, the surface of the piston ring obtained was nitrided. In the nitrided regions, a hardness ...
